Information

On January 7th, the utility model patent of "waterproof seam structure" applied for by Jiaguushi was approved by the State Intellectual Property Office. Patent No.: ZL 2021 2 1875853.1.

In practice, in order to avoid the influence of temperature changes, uneven foundation settlement and earthquake and other factors, structural displacement, so there will be deformation joints in advance, to avoid the damage caused by the deformation of the structure, to ensure the safety of the building structure.

For deformation joint part of waterproof design, generally use rubber water belt, foam rod, but limited by construction level, this kind of waterproof method is difficult to accurately positioning and effective protection, more damage or displacement, and become leakage weak link, it is easy to appear leakage, and repeated leakage, harm to the safety of building structure.

The utility model patent provides a waterproof joint structure of the building deformation joint, first cutting the concrete base surface where the deformation joint is located, with several grouting holes at the bottom of the groove, and acrylic grouting; quick condensing water nonleakage layer, epoxy mortar layer and epoxy adhesive layer on the groove bottom wall and side wall, and finally sealed rubber water stop and steel plate strip.

Acrylate slurry can be poured into the fine cracks in the concrete foundation, close the inner cracks; the fast condensing water leakage layer quickly block and close the water stop needle to prevent concrete seepage and moisture resistance; better and effectively prevent leakage risk of deformation joints; epoxy adhesive layer improves the bonding force between layers and bear certain back water pressure; rubber water stop to achieve water expansion and further enhance its waterproof function.

The waterproof joint structure of the utility model can effectively solve the problems of the repeated leakage and poor durability of the deformation joint, so as to inhibit the leakage phenomenon of the deformation joint, with lasting waterproof protection effect and good stability.

Up to now, Jiagushi has applied for more than 80 + patents, 39 invention patents, 5 of which have been authorized, and 42 utility model patents (36 of which have been authorized).In the future, Jiagushi will forge ahead and pay more attention to scientific and technological innovation while forging ahead, so as to realize the transformation of more new technologies, new materials and new technology achievements, and boost the development of the industry to a new level.
